WinReducer EX-70 is a useful tool for modifying the Windows 7 installation disc. Using it, we will customize the installed operating environment, removing unnecessary components from it and adding components that we would have to install manually at a later stage. One of the basic functions of WinReducer EX-70 is the ability to reduce the image size of the installation disc by removing unnecessary elements such as fonts, drivers, language versions, graphics compositions, etc. from its contents. On the other hand, the tool allows the user to integrate with the installation media their own mouse pointer, graphic motifs, wallpapers, as well as any applications, drivers, system updates and additional language versions. Importantly, once created, the configuration can be saved on the disk and used in subsequent modification operations. If you decide to modify the installation disk of the system, you will only need an ISO image of this medium or files copied from it in the traditional way. For proper operation of WinReducer EX-70, additional applications may be required, the location of which should be indicated on the disk at the first launch of the tool.
